happiness, less traffic noise, cleaner air and better social integration. yesterday during the bike ride i noticed that the americans, the san franciscans who cycled with us, they met a lot of fans. they were constantly waving and saying hi, hello, and how are you? and in a car, well, with the speed you're going, it's difficult to recognize who you're approaching and to say hi, the car is on the next block. on the bicycle you can see each other, wave, call each other in the evening saying well, what were you doing at the wiggle? economic benefits -- well, all these benefits i mentioned are also to be translated into economical benefits. as was mentioned, for the shopkeepers, the psychists are very good. at -- cyclists are very good.
